输入已经消除左递归的以及提取公共左因子的LL(1)文法，再输入相应的表达式，若分析成功，则在递归输出过程中输出"acc",若不成功，则有相应的报错以及位置指名。注意，要把同一个非终结符的产生式分成单个输入。他会自动计算first,follow,预测分析表的构造，但并不输出。-importation has been eliminated and left recursive public from the left-LL (1) grammar, further importation of the corresponding expression, if the analysis is successful, the output of the recursive process output "belongs", if successful, there were errors and the corresponding location named. Attention, we should end with a non-escalation of production into a single input. He will be automatically calculated first, follow, and predicting and analyzing the table structure, but does not export.

LEX程序 用来生成词法分析器-LEX procedure uses for to produce the morphology analyzer

是一个不错的语法分析器,里面实现了语法分析的算法,并判断了一些优先级的控制和对栈的操作.-is a good parser, they achieved the syntax analysis algorithms, and a judgment of priority to the control and operation of the stack.

词法分析器，用于输入表达式后输出单个独立的数据项-lexical analyzer for the importation of expression output of a single independent data item

对pl0语言的词法分析程序，带分析工具flex。输入一个PL0源程序文件名，即可看到词法统计结果。- To the pl0 language lexical analyaer, brings analysis tool flex. Inputs a PL0 source program filename, namely as worthy of looking at as morphology statistics result.

Tiny C&C++,看看吧,也许用的着-Tiny C

这是一个编译器的程序代码- This is a compiler procedure code

一个简单的编译器，可以实现简单的画图语句的解析，最终画出简单的图形。涉及程序编译器的实现几个步骤，词法分析，语法分析，语义分析，等等。-a simple compiler can achieve a simple drawing of analytic statement, the final draw simple graphics. The procedures compiler in several steps, lexical analysis, grammar analysis, semantic analysis, and so on.
